Just like the Sun, other stars also exhibit differential rotation. Currently, the rotation profile of a star that hosts a transiting planet can be estimated if during a transits, the planet occults a spot on the photosphere of the star, causing slight variations in its light curve. By detecting the same spot during a later transit, the stellar rotation period at that latitude is determined. Here, we present the results of differential rotation for 48 stars, 13 from the spot transit mapping method, while the remaining 35 stars from other techniques. The results show that the differential rotation is correlated with the stellar mean rotation period for fast rotating stars and strongly anti-correlated for slow rotators. The transition occuring at rotation period of 5 days. On the other hand, the differential shear increases with effective temperature for fast rotating stars, but the correlation is lost for the slow rotators.

Kesselheim proposes doubling the NIH’s budget to promote clinically meaningful pharmaceutical innovation. Since the effects of a previous doubling (from 1998-2003) were mixed, I argue that policymakers should couple future budget growth with investments in experimentation and evaluation.

This article argues that ritual remains a potent instrument for the generation of national identity and citizenship in Southeast Asia. We focus our analysis on the ritualisation of public space in Bangkok, Thailand, under the military-led government of General Prayut Chan-o-cha. The authors provide an ethnographic analysis of Sanam Luang, arguing that between 2016 and 2017 funeral rites held in this public space would reanimate it as a catalyst of national unification. As in other cases of ritual in public space, however, the intensified securitisation and control over national mourning for King Bhumibol by the military government, gave way to a range of reactions, including increased protests and criticism of the ruling government and Thailand's lesé-majesté laws by a predominantly youth-led movement in 2020.

John T. McGreevy's chronicle of modern Roman Catholic history is a vivid and sometimes jarring reminder of the historical depth of contemporary divisions within the Church, especially as these enter the public sphere. Catholicism: A Global History from the French Revolution to Pope Francis elucidates the church's ambivalent response to the challenge of modernity over the long nineteenth and twentieth centuries, specifically the rise of democratic nation states, anti-colonialist movements from the global south, the struggles of poor and working people for liberation, and feminist and human rights movements. The spread of totalitarianism and the supposed triumph of capitalism represented a different set of challenges for the church in this period.

This article explores Herodian's History of the Roman Empire alongside Chariton's novel Callirhoe with an eye to how the minds of collective entities are represented and function in the two narratives. It argues that Chariton, unlike Herodian, elaborates on the diversity of emotions that characterizes a specific collective experience and has groups use direct speech throughout. These choices add vividness to the narrative and intensify the fictional sensationalism and dramatic character of the novel. It also shows that, whereas collectives in Chariton's narrative are primarily designed to highlight a specific characteristic of a hero, dramatize an event and enhance suspense, in Herodian's historiography they are an integral part of the plot and central to his historical analysis of contemporary political and social world. This article offers a new analytical tool geared towards the development of a poetics of the collective in ancient narrative as well as a poetics of fictional and factual narration in antiquity, and advances our understanding of the complex relationship between ancient historiography and novelistic writing.

. Post-starburst galaxies (PSBs) have quenched (significant decline in star formation rate) both recently and rapidly (≲Gyr). They are thus promising in providing insights into activities that are happening at the early stage of quenching. While studies have suggested that black hole feedback in the form of active galactic nuclei (AGN) and outflows play important roles in quenching, the details of how they impact the host galaxies and their interplay with other quenching mechanisms are still not fully understood. We find that PSBs commonly show signatures of AGN activity but they appear to be weak and/or heavily obscured. These AGN might be able to drive outflows but they are likely not strong enough to remove gas from the host galaxy. Direct evidence of AGN quenching the star formation of the host galaxy is still missing and AGN likely quench by disturbing rather than expelling the gas.

This article examines audio-visual discontinuity in Ognjen Glavonić's 2015 documentary Depth 2 and argues that this approach to sound and screen allows the audience to engage with the difficult topic of war crimes in a novel manner in order to address a failure in cultural memory in Serbian society. The documentary explores war crimes committed against Kosovo Albanian civilians by Serbian state forces and paramilitaries in the spring of 1999. Depth 2 cinematically recontextualizes recorded testimonies of both survivors and perpetrators from the International Criminal Tribunal for the former Yugoslavia (ICTY), defamiliarizing the archive by anonymizing the source material and by removing the synchrony between voice and image. The lack of concordance between voice and screen is a key aesthetic strategy through which the film comments on pressing ethical, political, and historical issues in Serbian society.

Election skepticism has become a persistent feature of American politics since the Obama era. Such beliefs are most prevalent among White Americans and especially Republicans, and they are resistant to change. Conspiracy theory studies have shown that such beliefs are linked to feelings of ingroup victimization, at times associated with election loss. We draw on theories of White ingroup processes to argue that White grievance—the belief that Whites are victims of discrimination—is a key correlate of election skepticism among White Americans. White grievance was employed in the Obama era, but it was weaponized by Trump in the 2020 election. Our results based on four national datasets (2012–2020 ANES, 2021 YouGov) show that controlling for negative outgroup attitudes and other factors, White grievance is a significant predictor of election skepticism in all four studies. In 2020, the effect is stronger among White Republicans and independents. We also show that White identity/consciousness has the opposite effect, generally boosting trust in elections. Furthermore, a lagged dependent variable model using the 2016–2020 ANES panel shows that White grievance remains significant even after an LDV is included in the model.
